Beef and broccoli is a takeout favorite, and this crockpot version makes it easy at home. Thin slices of flank steak cook low and slow in a savory, slightly sweet sauce, then fresh broccoli goes in near the end so it stays bright green.
The recipe is sized for two people. That means no giant pot of leftovers and no pile of dishes. Prep takes about 20 minutes, and the slow cooker handles the rest.
Jump to RecipeWhy This Beef and Broccoli Works
A quick sear is the first secret. Browning the beef for 2 to 3 minutes before it goes into the crockpot builds a deeper, roasted flavor that you cannot get from the slow cooker alone.
The sauce is the second. Soy sauce, oyster sauce, brown sugar, garlic, ginger, and beef broth create the rich, salty sweet flavor you expect from a restaurant. Warming the sauce in the same skillet you used for the beef picks up all the browned bits left in the pan.
Timing the broccoli is the third. If it cooked for 4 hours, it would turn gray and mushy. Adding it in the last 30 minutes keeps it tender but still crisp.
Ingredients and Easy Swaps
- Flank steak: One pound, thinly sliced against the grain. Sirloin or skirt steak also works. Many stores sell pre-sliced stir fry beef to save time.
- Soy sauce: Low sodium soy sauce keeps the dish from getting too salty. Use tamari for gluten free.
- Oyster sauce: It adds savory depth. Hoisin sauce is a sweeter swap.
- Brown sugar: Honey works too. Start with a little less and taste.
- Garlic and ginger: Fresh tastes best. Jarred minced garlic and ginger paste are fine shortcuts.
- Broccoli: Fresh or frozen florets both work. Frozen broccoli may need a few minutes less.
- Cornstarch: Only needed if you want a thicker, glossy sauce. Arrowroot powder works the same way.
How to Make It at a Glance
- Sear the beef slices in olive oil over medium high heat for 2 to 3 minutes. Move them to a 3 to 4 quart slow cooker.
- In the same skillet, warm the soy sauce, oyster sauce, brown sugar, garlic, ginger, and broth until the sugar dissolves.
- Pour the sauce over the beef, stir, and cook on low for 4 hours or high for 2 hours.
- Stir in the broccoli about 30 minutes before serving.
- For a thicker sauce, stir in a cornstarch and water slurry and cook 10 to 15 minutes more.
- Serve over rice with sesame seeds and green onions.
Common Mistakes to Avoid
- Slicing with the grain. Look for the long lines in the steak and cut across them. This makes each bite tender instead of chewy.
- Crowding the skillet. Sear the beef in two batches if needed. Too much meat in the pan steams instead of browns.
- Adding the broccoli too early. Wait until the last 30 minutes for the best color and crunch.
- Dumping in dry cornstarch. Always mix it with cold water first, or it will form lumps.
A quick tip for slicing: put the steak in the freezer for about 20 minutes before cutting. Slightly firm meat is much easier to slice thin and even.
Variations
- Spicy: Add 1/2 teaspoon of red pepper flakes or a spoonful of sriracha to the sauce.
- More veggies: Add sliced red bell pepper, snap peas, or mushrooms with the broccoli.
- Sesame: Stir in 1 teaspoon of toasted sesame oil right before serving for a nutty flavor.
What to Serve With It
- Steamed white or jasmine rice: It soaks up all the sauce.
- Egg rolls or potstickers: Easy freezer add-ons that make it feel like takeout night.
- Cucumber salad: Something cool and crisp balances the savory beef.
- Noodles: Lo mein or ramen noodles are a fun change from rice.
Make Ahead, Storage and Reheating
You can slice the beef and mix the sauce up to a day ahead. Keep them in separate covered containers in the fridge.
Leftovers keep in a sealed container in the fridge for up to 3 days. Reheat in the microwave or in a skillet over medium heat until hot, adding a splash of water if the sauce is thick. The broccoli will soften a bit on reheating, but the flavor stays great. You can freeze the beef and sauce for up to 2 months, though the broccoli is best added fresh.
FAQ
Can I skip searing the beef?
Yes, if you are short on time. The dish will still be good, but searing adds a lot of flavor.
Can I double this recipe?
Yes. Double everything and use a 5 to 6 quart slow cooker. The cook time stays about the same.
Why is my beef tough?
It was likely sliced with the grain or needs more time. Flank steak gets more tender the longer it cooks on low.
Can I use frozen broccoli?
Yes. Add it straight from the freezer in the last 20 to 30 minutes. There is no need to thaw it first, but drain off any extra water so the sauce does not get thin.
What size slow cooker should I use?
A 3 to 4 quart slow cooker is the right size for this small batch. A bigger one can cook the sauce down too fast.
